All glass and metal on the outside, within, the Gibson seems heavily influenced by the look of the Starship Enterprise in the glory days of Jean Luc Picard. Stroll along the hushed interior, turn several corners, presto, you've arrived at the -- deep breath -- Hemidemisemiquaver bar, which turns out not to be named after the volcano that spat a 100-mile ash plume over European airspace last spring.

In fact, as Wikipedia informs us, a 'hemidemisemiquaver' is actually a musical note of one 64th the duration of a whole note. Er, quite. Anyway, the bar is all wide-open spaces and gobsmacking city views.

There is a whiff of Japanese minimalism about the place, though neon bucket seats offset any potential drabness. Still, if you fancy a pint before a show at the nearby O2, it's hard to think of a better option.
